AIR-COOLING DEVICE FOR MULTI PLE MOTORS.

Application filed May 7, 1923.

[0 all whom it may concern:

Be it known that I, LUDWIG GLANZER, a citizen of United States, residingat WVinkler, in the county of Riley and State of Kansas, have inventedcertain new and useful Improvements in Air-Cooling Devices for MultipleMotors, of which the following is a specification.

This invention relates to improvements in devices for cooling internalexplosion motors, particularly to types in which two or more motor unitsare arranged side by side and operatively engaged upon a common shaft,and more specifically to motors made in accordance with my co-pendingapplication, filed April, 1923; Serial 634,225, Rotary explosionengines.

One of the objects is to provide a casing or hood arranged to completelyenvelop the motor units so that a current of air, produced by a fanblower disposed between the units and driven direct by the motor shaft,is caused to circulate around each motor frame dispelling the heattherefrom.

Another purpose is to produce a hood that can be easily and quicklyraised and removed in case of necessity or convenience, as ininspecting, adjusting or repairing the motors.

A further aim is in the provision of means combined with the hood forprotecting the spark plugs against injury and through which they arereadily accessible.

These aims and objects are attained by the novel construction andcombination of parts hereinafter disclosed and shown in the accompanyingdrawing, forming a part hereof, and in which Figure 1 is a top plan viewshowing a casing or hood made in accordance with the invention.

Figure 2 is a side elevational view of the same, partially broken awayto illustrate its application.

Figure 3 is a transverse sectlonalvlew taken on line 3-3 of Figure 1 anddrawn to an enlarged scale.

In the drawing the numeral 10 designates a platform on which is mounteda pair of motor units 11, each being composed of a pair of rotors havingindependent connections with the inlet manifold 12 and outlet manifold13, the former of which receives its gas through the rectangular tube14, the exhaust gases passing out of a similar tube 15.

Serial No. 637,185.

All of the several motors are connected with a common shaft 16,horizontally mounted in bearings 17 secured to the platform 10 andhaving a transmission gear 18 at one or both ends.

Midway between the motor units 11 is a space 19'c0ntaining a broad facedfly wheel 20 having a web 21 at its center and lateral spokes 22 flushwith the edges of the wheel rim, the hub being fixed on the shaft 16 torotate with it.

Fixed on the periphery of the wheel are a plurality of extending vanes23., equally spaced apart and formed at angles, the apex of which isdirected in the direction in which the wheel isrotated, thus presentinga herring bone appearance adapted to force air equally in oppositedirections.

This wheel is preferably of such diameter as to extend through anopening in the platform, as shown in Figure 3, to gather fresh cool airin its vanes for cooling the motors.

The casing or hood, generally designated by the numeral 2 1, is composedof a top plate 25 extending completely over the entire motor structureand curved at its edges to blend into the side walls respectively 26 and27, joined by end'walls 28, all of said walls extending downward overthe edges of the platform on all sides and secured to them by wingscrews 29.

The front plate 26 contains recesses 30 adapted to clear the inlet andoutlet connections 14: and 15 and a central recess 31 extends in fromboth side edges to admit air to the fan or vane wheel.

The spark plugs 32 employed on the motors extend upward within the wells33, the walls of which are open at both ends and secured level withinthe top plate 25.

From the foregoing it will be seen that an effective device for thepurpose has been described in the preferred form of its embodiment, butit will be clear that minor changes may be made without departing fromthe scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. The combination with a pair of spaced rotary motors operativelyengaged on a common shaft, a platform on which said motors are mounted,a flywheel on the shaft between said motors, a series of herring bonevanes on the periphery of said fiy-wheel, and a casing disposed oversaid wheel and motors, said casing being removably enadapted to forceair laterally outward, and
